While at the mall, Daffy ends up trying to get an ice cream store lady to use the tips to pay for the sundae which doesn’t go well. Daffy later learns that Bugs earns his money from an invention he made called the Carrot Peeler. After learning this fact, Daffy decides that a good invention is the perfect get-rich scheme. He gets to work in the garage “inventing” items that have been around for ages. Since inventing is such hard work, Daffy goes for the quick and the dirty, stealing an idea from Bugs’ notebook called the Automatic Carrot Peeler. Daffy ends up succeeding causing a reversal of luck on Bugs who ends up moving back to his rabbit hole in the forest. Daffy rakes in plenty of money at first, but when public complaints about the Automatic Carrot Peeler being flammable (since Daffy never fully completed the instructions to the Automatic Carrot Peeler, forgetting to add in the cooling system to prevent this) rise and threaten both their lives with the city planning to repossess their home, Bugs get them both out of a huge mess by using a time machine to go back in time to pay for Daffy’s sundae and not mentioning about him inventing the Carrot Peeler; however this is a paradox since there’s still Bugs’ past self around. Some time later, Daffy Duck goes back in time to show some cavemen the toilet paper which he throws to them. The toilet paper lands on the head of one of the cavemen causing them to attack Daffy.
